震前应变固体潮畸变的物理模式

本文根据岩石力学及固体潮理论，建立了孕震期弹性物体应变固体潮的物理模式，给出了其数学公式。通过分析潮汐应力与寻震应力的合力随潮汐力相位的变化，从物理本质上讨论了不同应力阶段应变固体潮曲线的形态特征；讨论了震前不同异常时期，应变固体潮畸变的不同特．点；并对震例进行了分析，同时，对应变固体潮畸变与地震三要素预报作了初步探讨。

PHYSICAL MODEL ON DISTORTION OF THE STRAIN EARTH TIDE BEFORE EARTHQUAKE

Based on the rock mechanics and earth tide theory,a physical model on strain earth tide of the elastic medium during seismogenic process has been given,and the mathematics formulas on it have been given. Based on analysis of the change of the resultant stress of the eanth tide stress and seismogenic stress with the phase of earth tide stress,the form characteristics of the curves of strain earth tide in different stage of the stress has been discussed in physical substance. The different characteristic of distortion of the strain earth tide during different anomalies before a earthquake has been discussed, and some sample of the earthquake have been analysed, besides distortion of the strain earth and the three essential elements of the earthquake prediction have been preliminaily discussed.
